Abstract

A vehicle body has, in a state in which a battery unit is not installed, a frame configuring a part of the lower surface of the vehicle body. A vehicle battery unit installation apparatus for installing a battery unit in the lower part of the vehicle body includes: a striker device configured to be secured to the vehicle body and a locking device secured to the battery unit. The striker device includes a base plate and a striker secured to the base plate. The striker has a support part capable of supporting a load. The locking device is capable of securing the support part. The base plate is configured to be secured to the frame. The striker has ends secured to the base plate such that the support part is located below the frame.

First claim

The invention claimed is:

1. A vehicle battery unit installation apparatus for installing a battery unit in a lower part of a vehicle body, wherein the vehicle body has a frame configuring a part of a lower surface of the vehicle body in a state where the battery unit is not installed, and the vehicle battery unit installation apparatus comprises:
a striker device configured to be secured to the vehicle body, wherein the striker device includes a base plate and a striker secured to the base plate, and wherein the striker has a support part capable of supporting a load; and
a locking device secured to the battery unit and capable of securing the support part, wherein
the base plate is configured to be secured to the frame,
the striker has ends secured to the base plate such that the support part is located below the frame and wherein at least a portion of the base plate is disposed above the support part and below the frame along a vertical line passing through a cross section of a centroid of the frame in a state where the battery unit is installed in the vehicle body,
the frame has a pair of frame side walls and a frame lower wall connected to lower ends of the frame side walls,
the base plate has a base plate lower wall extending substantially parallel to the frame lower wall and secured to the frame lower wall, and
at least a first end of the striker extends upward from the support part, extends parallel to the base plate lower wall, and is welded to an upper surface of the base plate lower wall.

2. The vehicle battery unit installation apparatus according to claim 1 , wherein
the base plate has a base plate side wall formed by bending and extending an end of the base plate lower wall along the frame side walls, and
a second end of the striker extends upward from the support part and is welded to the base plate side wall.

3. The vehicle battery unit installation apparatus according to claim 1 , wherein
the base plate is secured to the frame with a plurality of bolts, and
the frame is provided with a back plate jointed with the base plate by means of the bolts.

4. The vehicle battery unit installation apparatus according to claim 1 , wherein
the locking device includes:
a housing having an entering opening enabling entering of the support part;
a latch pivotally supported about a first swing shaft center with respect to the housing and enabling switching between a locking state, in which the support part is locked in the entering opening, and a released state, in which the support part is released in the entering opening; and
a pawl capable of regulating swing of the latch, wherein
the latch is located on the vertical line passing the centroid in the cross section of the frame in the state where the battery unit is installed in the vehicle body.

5. The vehicle battery unit installation apparatus according to claim 4 , wherein the pawl is pivotally supported about a second swing shaft center with respect to the housing between a first position, at which swinging of the latch can be regulated, and a second position, at which swinging of the latch can be allowed,
the vehicle battery unit installation apparatus further comprising a lock releasing part configured to swing the pawl from the first position to the second position.

6. The vehicle battery unit installation apparatus according to claim 1 , wherein
the frame includes a plurality of side members extending in a longitudinal direction of the vehicle body,
the base plate is secured to each of the side members, and
the locking device is provided on a side surface of the battery unit.
